Marketplaces and Matching
建立模型分析存在市场且商品有差异时的交易模式，发现稳态下市场一侧的未匹配交易者只能与另一侧的新流入交易者匹配，并用英国就业中心的求职者与职位空缺数据验证。
This paper models trading patterns when marketplaces exist and goods are differentiated. When first visiting the market, a buyer samples a stock of goods. If fortunate, the buyer finds a match, purchases one of these goods and then exits. If not, the buyer can now only match with the flow of new goods. In a steady state, the stock of unmatched traders on one side of the market is trying to match with the flow of new traders on the other side. This behaviour is shown to describe matching patterns between unemployed job seekers and vacancies in U.K. Job Centres.
